How to Convert Watt to Megawatt

1 watt = 1 × 10-6 megawatts

Megawatt = Watt × 1 × 10-6

Example: 0.045 W × 1 × 10-6 = 4.5 × 10-8 MW

Reverse Conversion

To convert megawatts back to watts:

  • Remember, 1 megawatt equals 1000000 watts.
  • To convert 4.5 × 10-8 MW to W, multiply 4.5 × 10-8 x 1000000, resulting in 0.045 W.
